This invention has to do with a road roller construction and it is a general object of the present invention to provide a general road roller construction which is simple, practical and convenient to operate.

This application is division of my copending application entitled Road Roller filed March 30, 1946, Serial No. 658,507, in which application I specifically claim a road rolling vehicle including its drive. I

' It is a general object of my present invention to provide a road roller of improved construction wherein the forward portion of the frame is in the nature of a head which not only effectively supports the yoke of the steering roller but also carries the mechanism of the steering gear and forms a convenient advantageously located seat on which the operator can ride. With the. ar-

rangement that I have provided the seat formed by the head of the frame is located in a most.

convenient and advantageous manner relative to the steering wheel and relative to the controls so that the machine as a whole is compact and convenient to manipulate. The various objects and features of my invention will be fully understood from the following detailed description of a typical preferred form and application of the invention, throughout,

which description reference is made to the accompanying drawings, in which:

Fig. 1 is a side elevation of the road roller embodying my present invention; Fig. 2 is a plan view of the forward portion of the vehicle; and Fig. 3 is a transverse sectional view taken as indicated by line 3-3 on Fig. 1.

The road roller or vehicle that I have provided involves, generally, a frame A, two rollers that support the frame, one a main drive roller B and the other a steering roller C, a steering gear D for the steering roller C, a storage tank E preferably located in the region of the drive roller B, a prime mover F, a clutch unit G, a transmission or speed change mechanism H, and a direct drive means J from the transmission H to the drive roller B.v

The frame A that I have provided is of simple, inexpensive, yet effective construction. It involves, generally, two spaced parallel side rails [0, a platform ll carried between the side rails at the forward end portion thereof, and a head l2 carried by the forward ends of theside rails. The rails 10 may be simple, straight, horizontally disposed beams and the platform Il may be a simple, flat plate extendingbetween and anchored to the beams. 1 v 1 e application June 23,

' '18Claims. (Cl.280106) The head l2 of the frame forms a mounting for the steering roller C, or at least forms a part of the frame to which the steering roller is attached, and in accordance with my construction it involves, essentially, two spaced side plates l3, one carried by each of the beams! 0, which plates extend up and forward from the beams in the manner clearly shown in Fig. 1. The head further includes a plate that extends between the side plates I3 and has a vertical section H extending upwardly from the forward end of the platform II to a point a substantial distance above the platform and a horizontal section l5 which extends forward from the upper end of the section [4 between the plates I3 to a point where it joins a transverse head beam 16.

' The section I4 may be located somewhat forward of the vertical edges I! of sides l3 and the section 15 may be located somewhat below the topedges [8 of the sides I3. The sections I4 and I5 are preferably secured, for instance, welded, to the sides It where they adjoin them and these parts thus form 'a rigid durable frame construction. e

The head beam I5 is preferably a tubular part extending between the forward end portions of the side plates l3 and has its ends joined thereto while the forward edge of the plate section I5 is preferably joined or welded to the beam I6. It is to be observed that the horizontal section conveniently located and arranged seat or support for a seat cushion, or the like, on which an operator can sit while his feet are on the platform II.

The main or drive roller B is preferably a large.

roller and is preferably designed so that it can be weighted with water, or the like. In the construction illustrated the roller includes a cylindrical rim 20 with end plates 2| closing it at the" roller B operates between the beams 10. 1

The steering roller C maybe a simple drum-,- like structure involving a rim 25 and end, plates 26 closing the endsof the cylindrical rim. The

rollerC is carried by, a yoke 21 which ,is pr-o,-. I vided with a king or pivot pin 29 that is pivotally. connected to the head beam l6 ofvthe frame.

l5 of the head construction just described forms a d The head beam 16 is preferably provided with a downwardly facing boss 30 against which the yoke seats. The arms of the yoke that carry the roller C depend down at either end of the roller and they may carry a frame 3| supporting scrapers 32 as shown in Fig. 1. b The steering gear D is provided for steering or turning the roller C about the pivot pin 29 and it is preferably carried by the horizontal sec tion I of the frame head and somewhat to one side of the center of the vehicle so that it does not obstruct the seating area provided by the section l5. The steering gear that I have shown involves generally, a hand wheel 33 on the forward end of a horizontally disposed drive shaft 34 which drives a vertical shaft 35 through a suitable gear drive 36. The shaft St is located above the plate section l5 and projects somewhat forward there of so that the wheel 33 is supported a short distance forward of the plate section l 4, while the shaft 35 extends down through the plate section and "s operativelyconnected with the yoke 21 through 9. suitable link mechanism 38 so that whenth'e shaft is rotated the yoke 2"! is turned oh th'e pivot pin 25. I

The storage tank E is preferably located over the drive roller B and is preferably shape'd to nest over the drive roller B. In the case illuse trated the tank E involves fiat ends 40, vertical fiat side's'La flat top 42 and a concave bottom 43 which'conforms to the curvature of the rim .20 of the roller B. A filling opening is provided in the to of the tank and is normally closed by a plug 44 and a suitable drain opening is provided in the lower part oft-he tank and is qrmuy closed by a plug '45. Thetank just describedis supported on the beams I0 so that the loader weight thereof is communicated through the beams to th'eroller B. Suitable hoses or pipe finestlead from the tank to the rollers B and iCs o water can be supplied to the rollers as the machine operates. V V

"he prime mover F that I have provided is preferably an engine such ras an internal coinbustio'n'engine and'it, together with "the clutch means and a change speed transmission, formsa unit that is disposed transversely of the vehicle in the space that occurs between the tank of means E and the section M of the head of the frame, it being preferred to locate this u'nit i'mmediately adjacent the tank so that there is'space between the unit and the head of the frame where the operator can conveniently stand, which space is convenient to the steering wheel 33. The unit formed of the parts just described is preferably carried by a pair of supports that extend transversely between the beams '10 to the desired point "so that they effectively carry the unit.

I prefer to employ a reversing clutch such as I set forth and claim in my co-pending application, which clutch includes two elements, one engaged to operate the vehicle in one direction and the other engaged to operate the vehicle in the opposite direction.

4 to be convenient to the operator in substantially the same manner as member 63.

The drive means J that I have provided between the power unit above mentioned and the roller B is preferably a simple direct drive which effects a substantial speed reduction between the shaft 14 of the unit and the roller. The shaft 14 has an extension at the exterior of the housing 10 which extension carries a drive sprocket 8|. A driven Sprocket 82 is carried by the roller B and a chain 83 connects the sprockets 8| and 82. It be observed from the drawings that the sprocket, 8 2 is very much larger than the sprocket 84 with the result that a substantial speedreiduction. is, effected in the course of the drive from the transmission to the roller.

From the foregoing description it will be apparent, that I have provided a vehicle or roller that can be varied in action by varying the material carried within theroller B and further, it will be "observed that the principal working parts are confined to the unit formed by the engine, clutch means and transmission, and that this unit is arranged convenient to the operator and transverse of the vehicle. The only exposed drive parts are the chain and sprockets and, in practice, these may be housed by'suitable guards '90 and 91, if desired.

The shift levers 63 and 88 are convenient to the operator as is thehand wheel '33 by which the vehicle is steered. The operator can either-sit on the liorizontal section it of the frame as the vehicle is being operated, or he can stand Q11. the platform H as he desires. In manipulating the vehicle the transmission is normally set at either one speed or the other by sh; nfgthe member tooneextreme position "or the other. With the transmission thus set it 'can be left alone and it determine the general speed "of the roller except, of c e, for cont ol car dj liroush he speed at which the engine is op ted.
